M. E. BRANTHAVER IEANS FOR LIQUID TREATMENT OF ROASTED ORES Filed May 10, 1924 I Quorum:

ing the copper sulfate and like soluble constituents without however, heating the water to such a degree that it will be incapable of affecting physical shattering of the residue, (non-soluble metallic and silicious materials) it being noted that the water of the bath is being constantly changed. A suitable traveling conveyor D, preferably one having scraperblades cl which in their operative run ing from the furnace and toward said deeper not be disclosed herein.

travel along the floor 0, causes the discharge, 7

along with the elements in solution, ofcthe gangue and metallic elements wlnchare not in solution, over the top of the vat. The various elements and thos-ein solution are now in Having thus described the invention, what I believe to be new and desire to secure by.

Letters Patent, is.:-; I

, .1. An ore roasting furnace having its roast- .ing chamber provided with a duct through which the hot roasted ore is discliarged, a vat containing water whose level is such as-to seal thedischarge end of said duct and whose depth adjacent said'discharge end is such that the" ore will be submerged therein when it leaves the duct, and means for injecting water into the ore within the duct.

. 2. An ore roasting furnacerhaving an ore discharge opening, a liquid containing vat of varying depth correlated with the discharge openin'gto position a relatively deeper part of the vat beneath said discharge opening, and I meansarranged in the discharge opening for directing a current of liquidinto the ore passpart of the vat. in p '3. An ore roasting furnace having an ore dISChHI B o enin a li uid containincr vat of D 237 as varying depth correlated with .the discharge -opening to position a relatively deeper part of the vat beneath said. discharge opening,

. means arranged in the discharge opening for directing a current of liquid into the ore pass- I ing from the furnace and toward said deeper part of the vat and means for conducting the solid constituents of the ore from said deeper part of the vat and discharging the same over the top of the latter. 7 Y

. 4. An ore roasting furnace having an ore discharge opening and a liquid containing vat having an inclined floor correlated with said discharge opening to position the deepest part or the vat beneath said opening, means correz lated with the discharge opening and vat to direct a stream ofcool liquidintoithe ore pass the deepest part of the vat, and means opera tively related with the floor of the vat to cause the solid constituents of the ore to be discharged over the top of the vat.

5. An ore'roasting furnace having an ore discharge opening, a vat to contain an orecooling liquid adjacent the discharge opening and means through which the supply of cooling liquid in the vat is replenished, said means arranged to direct the liquid into the ore adjacent the discharge opening from the furnace at a point and in a direction which forcesthe submersion of the ore in the cooling liquid.

6. An ore roasting furnace having an. ore discharge opening, a vat to contain anorecooling liquid adjacent the discharge opening and means to replenish thesupply of liquid in the vat,'said means arranged to' discharge the liquid into the. vat at a point below the level of the furnace floor and above the level of the liquid in the vvatand to project said stream into the ore at an' angle to create a downward drawinthe pool of liquid in the vat,

7. An ore roasting furnace havingv an ore discharge opening, a vat to contain anorecooling liquid so correlatedwith the discharge level whichwill seal said opening against the admission of atmospheric air, therethrough and will cause the vapors generated by contact opening that the cooling liquid will be at a i 'ofthe hot ore with the liquid to enter the fur-' nace through said opening, i and means through which the supply of cooling liquid in the vat isreplenished and its level maintained, said means arranged to direct theliq- .uid into the ore adjacent the discharge openioo ing from the furnace at a point and in a direction which "forcesthe submersion of the ore in the cooling liquid.

8L Anore treating meanscomprising'an ore roasting chamber having means through which the ore is discharged therefromand a liquid containing vat having means correlated with the ore discharge opening and vat to cause'a flow. ofliquid in, the vat and the sub- ,mersion of the ore in said liquid and the,cool-' ing and physical disruption ofthe ore, and a conveyor additional to said meansand traveling within the vat for discharging ore from he vat.

9. Anoretreating means, comprising an ore roasting chamber provided with means through which the ore is discharged therefrom, an ore submersion vat having its bottom arranged to supportthe ore and inclined upwardly and rearwardly from a point below the dischargemeans to a pointabove the level of said means,-means for causing a flow of liquid within thevat and a-convey'or traveling within the vat to scrape the ore along the bottom thereof and discharge it over the top of the'vat. 1 ing from said discharge opening and toward I 10. An ore treating means having aroasting chamber provided with means through which the roasted ore is discharged from the chamber, an ore submersion vat correlated with said means to seal the same against the ingress of air therethrough and to receive the ore therefrom, the end of said vat adjacent the discharge means being of such depth that V the ore will be submerged in the liquid of the vat and the bot-tom of the vat being arranged to support the ore and being inclined upwardly from said end, means for causing a fiow of water within'the vat, and a traveling conveyor whose upper and lower runs are mthe tank and whose lower run scrapes the ore along the bottom of the vat and discharges it from said vat.

. In testimony whereof I aflizi my signature.
